The above toolholders have a 1.5º helix angle.
* V6 inserts cannot be used on standard internal toolholders without anvil. For this purpose you must use one of these special V6 toolholders.
The above toolholders have a 1.5º helix angle. For other helix angles, see page 10.

Calculating the Helix Angle
b
b
p
The helix angle is calculated by the following formula:
D
b = arctan P x N
x
D
b - Helix angle [ ° ]
P - Pitch [Inch]
N - No. of starts
D - Pitch diameter [Inch]
Lead = P x N
The helix angle can also be determined from the diagram below.
